Discovering a New Species of Frog in Southern Brazil
Hidden away in the mountains of southern Brazil, a vibrant orange frog, measuring just over a centimeter in length, has emerged as a newfound star.
The diminutive pumpkin toadlet represents a previously undescribed species of frog, adding to the rich biodiversity of the region.
This highly endemic frog species is exclusively found in a small area of mountainous forest, where it thrives amidst the leaf litter. Conservation efforts are urgently needed to protect this unique habitat and preserve not only this newly discovered frog but also its endangered counterparts.

The tiny frog resides at an altitude of over 750 meters within the Serra do Quiriri mountain range in the state of Santa Catarina, southern Brazil.
Belonging to the Brachycephalidae family, researchers have identified two closely related orange frog species, Brachycephalus auroguttatus, residing nearby in other pockets of the Serra do Quiriri mountains.
Over the past seven years, Brazilian researchers have been diligently documenting all Brachycephalus populations in the region, leading to the serendipitous discovery of this new species.
It was the distinctive call of the male frogs during mating season that eventually gave away the presence of this elusive species. The females, being quieter, were collected more sporadically.
Through meticulous genetic and morphological analyses in the laboratory, scientists confirmed the existence of a new species, now named B. lulai, as a tribute to Brazil’s former president Luiz Inácio Lula da Silva.
In a published paper, herpetologist Marcos Bornschein and his team from SĂŁo Paulo State University emphasized the importance of expanding conservation efforts to protect the Atlantic rainforest and Brazil’s unique miniature frog species.
While the newly discovered B. lulai species seems to thrive in a relatively pristine environment, urgent conservation actions are imperative for critically endangered frog species in Santa Catarina. Habitat loss due to activities like grassland burning, cattle grazing, invasive species encroachment, tourism, mining, and deforestation pose significant threats to these vulnerable amphibians.
Amphibians globally face a dire situation, being the most threatened vertebrate class on Earth.
Efforts are underway to establish a federal conservation unit in Santa Catarina to safeguard the region’s forests without necessitating the purchase of private land by the government.
The research team looks forward to further sampling of Brachycephalus species, which will enhance our understanding of species variation and aid in redefining species boundaries. However, challenges such as limited funding for field research and accessibility issues in remote mountainous locations continue to hinder comprehensive sampling efforts.
The groundbreaking study detailing the discovery of the new frog species B. lulai has been published in PLOS One.
